Open-domain dialogue generation has gained increasing attention in Natural Language Processing. Its evaluation requires a holistic means. Human ratings are deemed as the gold standard. As human is inefficient and costly, an automated substitute highly desirable. In this paper, we propose metrics that capture different aspects of open-domain dialogues. Our consist (1) GPT-2 based context coherence between sentences dialogue, (2) fluency phrasing, (3) n-gram diversity responses to augmented...

In the past decade, cybersecurity has become increasingly significant, driven largely by increase in threats. Among these threats, SQL injection attacks stand out as a particularly common method of cyber attack. Traditional methods for detecting mainly rely on manually defined features, making detection outcomes highly dependent precision feature extraction. Unfortunately, approaches struggle to adapt sophisticated nature attack techniques, thereby necessitating development more robust...

The success of advanced dynamic utilisation the scarce spectrum in cognitive radio depends upon reliable primary signal detection where accurate noise power estimation plays a critical role. However, practical scenarios, cannot be accurately estimated, which significantly degrades performance detection. To avoid inaccurate and associated accumulated problems. A novel two-stage Bayesian estimation-based energy algorithm is introduced here. This algorithm, as supported by simulation results,...

Key points Central hypercapnic hypoventilation is highly prevalent in children suffering from congenital central syndrome (CCHS). Mutations of the gene for paired‐like homeobox 2b (Phox2b) are aetiologically associated with CCHS and Phox2b present components respiratory chemoreflex, such as nucleus tractus solitarius (NTS). Injection neurotoxin substance P‐saporin into NTS destroys Phox2b‐expressing neurons. Impaired ventilatory response caused by this attributable to a loss CO 2 ‐sensitive...

The nucleus tractus solitarii (NTS) is implicated in the control of breathing, but neuronal phenotype and circuit mechanism involved such a physiological function remain incompletely understood. This study focused on respiratory role paired-like homeobox 2b gene (Phox2b)-expressing NTS neurons sought to determine whether selective stimulation this set activates breathing male mice. A Cre-dependent vector encoding Gq-coupled human M3 muscarinic receptor (hM3Dq) was microinjected into...

We extracted data on years lived with disability (YLDs) age-standardized YLDs rate (ASYR) related caused by smoking, including cataracts age-related macular degeneration (AMD), Global Burden Disease (GBD) database for 2021. These were disaggregated age, gender, sociodemographic index (SDI), region, country. Temporal...

Cognitive radio has been recognized as one of the most promising technologies dealing with scarcity spectrum. In cognitive system, spectrum sensing, secondary users are allowed to utilize frequency bands primary when idle. Hence, how accurately detect idle attracted many researchers' eyes. Energy detection is common method for band detection. However, improper energy threshold setting can dramatically affect performance system. There two types errors in sensing: false alarm and...

Abstract Artemisinin and its derivatives (ARTs) can kill malaria parasites, but mechanism remains unclear. Haem or iron (HI) was proposed to activate ARTs produce free radicals that parasites. However, our results revealed adding supply did not enhance the antimalarial effect of attenuated this effect, strongly suggesting radical only mechanism.

Abstract Electrocatalytic carbon dioxide reduction into high‐value chemicals is one of the important solutions to greenhouse effect and energy crisis. However, slow kinetic process eight electrons requires development efficient catalysts improve yields. Single atom (SACs) with high activity selectivity have become an emerging research frontier in field heterogeneous catalysis. Herein, a catalyst comprised Cu single atoms loaded on substrate (Cu‐NC) developed for highly selective...
